Optimization of Cement Grinding Operation in Ball Mills

Optimization of Cement Grinding Operation in Ball Mills

Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

Canadian Mineral Processors Examine the Fine Art of Grinding

Such mills are commonly used in the cement industry but only rarely for mineral processing. Crushed ore and hot gas are fed into the drying chamber of each mill where the moisture content is reduced to 0.5%. Dry ore passes through a diaphragm into the coarse grinding chamber where a charge of 4-inch chrome-steel balls reduces the size to -1/4-inch.

Flexible milling and grinding solutions that last FLSmidth

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
